They already have and failed... See big 12 calling arkansas. No team would leave the SEC now. Would be idiotic....
Funny. I never even considered SEC teams leaving for other conferences. They can have Vandy if they want them.
And this success itself is probably the only difference in fan bases, between being thought of as confident or even cocky and being so-called "arrogant." Kinda makes you want to go back and rethink all this "arrogant" Alabama stuff, eh?
I don't think anyone would benefit from leaving, and I also don't think it is arrogance to see it that way. The SEC has a very strong track record on the playing field, so I believe confidence is a more appropriate term.
